How multiple stressors (e.g., warming, drought, and elevated CO2) affect the performance of organisms, both directly via physiological/behavioral/functional traits and indirectly via species interactions, and how these effects scale up to influence the abundance and distribution, spatial patterns, food web structure, community composition, ecosystem productivity and biogeochemical cycling, etc.
How climate-driven phenological/geographical shifts and the resulting temporal/spatial synchrony/asynchrony influence the population dynamics of interacting species
